Electrical Connections; Earth Continuity Test; Level Regulators - Grindex Micro Installation, Care And Maintenance

Electrical connections

WARNING!
All electrical equipment must
be earthed (grounded). This ap-
plies to both pump equipment
and any monitoring equipment.
Failure to heed this warning may
cause a lethal accident. Make
sure that the earth (ground) lead
is correctly connected by test-
ing it.
Check that the mains voltage and frequence agree with
the specifications on the pump data plate.
Make sure that the pump is correctly earthed (ground-
ed).
WARNING!
All electrical work shall be car-
ried out under the supervision of
an authorized electrician.
Local codes and regulations
shall be complied with.

Earth continuity test

When performing the earth continuity test, measure be-
tween the earth wire in the motor cable and one of the
screws securing the strainer. See picture below.

Level regulators

Start and stop of the pump at different water levels may
be manual or automatic. If automatic start and stop is
required, a level regulator can be ordered (as option).
Level regulators are available for both 50Hz and 60Hz
markets.
The level regulator can be set at different operating lev-
els by adjusting the length of cable. A clamping bracket
situated below the lifting handle holds the level regulator
cable in place.
If continuous pumping is required at any time the level
regulator can be placed in a special rubber bracket on
the lifting handle thus eliminating the level regulator
function.

supply before mounting or dis-
mounting the cable or/and the
level regulator. Risk for electrical
shock.
